Please know that I created this class for a one-off project before I really knew how to use Git or how to support my code as an open-source contribution. Consequently, other users quite appropriately forked it and you will find more up-to-date (i.e., actually usable) equivalents elsewhere.
My goal in creating yet another DS1307 library was to provide easy access to some of the other functions I needed from the chip, specifically its square wave output and its battery-backed RAM.
@todo Mostly comments in
Examples (in /examples folder)
RealTimeClockDS1307_Test.pdeallow you to turn the clock on/off, set date/time, set 12/24h, [de]activate the square wave, and read/write memory from the Serial Monitor.
RealTimeClockDS1307.fzis a Fritzing breadboard layout showing the basic hookup of the Sparkfun RTC module to an Arduino. Included is an optional resistor+LED to show the square wave (note that it's an open drain, so you hook up to it rather differently than, say, pin 13).
- Reverse renaming of getDate() and setDate(), now getDay() is calling getDate() and setDay() is calling setDate()
- Readme improvements
- changed getDate() to getDay() and setDate() to setDay()
- updated keywords.txt
- updated example
- added keywords.txt for syntax highlighting
Version 0.92 RC
- Updated for Arduino 1.00; testing with Andreas Giemza (hurik)
- added multi-byte read/write
Version 0.9 RC
- initial release
- web page documentation
Much thanks to John Waters and Maurice Ribble for their earlier and very helpful work (even if I didn't wind up using any of their code):
